+# Release Notes
+
+## v2.3.0 — Frontend Security Auditing & Client-Side Secret Detection
+
+### Highlights
+
+Minor release adding frontend security auditing (CSP, CORS, cookies, SRI, XSS, open redirect, insecure forms, vulnerable CDN), client-side storage token detection, response header API key scanning, fingerprint state management library detection, and a comprehensive test suite for the scanner. All historical release notes have been rewritten in a user-friendly format.
+
+### What's New
+
+#### Secret Detection
+
+- **Client-side storage token detection** — Scans `localStorage`, `sessionStorage`, and `IndexedDB` references for stored tokens, secrets, and sensitive identifiers
+- **Fingerprint state management library detection** — Identifies state management libs (Redux, Zustand, Pinia, Vuex, etc.) used in client-side apps
+- **Response header API key scanning** — Scans response headers for exposed API keys and secrets
+
+#### Frontend Security Auditing
+
+- **CSP audit** — Evaluates Content-Security-Policy headers for weaknesses (missing directives, unsafe-inline, unsafe-eval, missing nonces)
+- **CORS audit** — Checks Cross-Origin Resource Sharing policies for overly permissive configurations
+- **Cookie security audit** — Inspects cookies for missing `HttpOnly`, `Secure`, and `SameSite` flags
+- **SRI verification** — Detects missing Subresource Integrity attributes on script and link tags
+- **XSS vulnerability scanning** — Probes endpoints for reflected XSS vulnerabilities
+- **Open redirect detection** — Identifies endpoints that allow unvalidated redirects
+- **Insecure form detection** — Flags forms submitted over HTTP instead of HTTPS
+- **Vulnerable CDN detection** — Identifies outdated or known-vulnerable CDN libraries
+
+#### Engine Improvements
+
+- **Comprehensive test suite** — Added thorough test coverage for scanner components, including secret detection, fingerprinting, and auditing modules
+
+### Documentation
+
+- Rewrote all historical release notes (v1.0.0 through v2.2.0-next) in a consistent, user-friendly format
+- Added missing release notes for v2.2.0-next, v2.2.0, v2.1.1, v2.1.0, v2.0.0, v1.1.6, v1.1.4, v1.1.1, v1.0.1, v1.0.0
